Texas in Africa: enough - 0 views

  • The fact that only a small percentage of the minerals used in cell phones actually come from the DRC, that the region is largely at peace now, and that the situation defies easy solutions, if mentioned at all, is typically buried in the group's more complex reports, or brushed aside.
  • the problem arises when simplification results in distortion, which is exactly what has happened here.This is probably why, despite being able to claim support at the national level from the country's Catholic bishops and a civil society organization or two, the conflict minerals platform lacks meaningful support from most CSO's in the Kivus.
  • My fear is that, as a direct result of Enough's narrowly focused advocacy campaign, Congress will now think it has taken sufficient action to end the conflict in the eastern DRC. That couldn't be further from the truth.
  • ...9 more annotations...
  • Everybody involved in this debate wants the same thing: to end violence in the eastern Congo. I want to believe that Enough's leadership and staff began their campaign with the best of intentions. But by overstating the extent to which American consumers are actually using Congolese conflict minerals - and the extent to which it is actually possible to change the way minerals are traded there - they've given Congress, the Congolese government, and the electronics companies an easy way out. All three groups will come out looking good here, while Congolese government officials will continue to benefit from the mineral trade, electronics companies will source the tiny percentages of Congolese materials they've been using elsewhere, and Congress won't feel obligated to support meaningful security sector reform, help sort out the country's land tenure issues, or significantly fund the hundreds of Congolese civil society organizations that have been working for years to bring about meaningful change in the region.
  • Also, I think you should divorce the attack on Enough from the critique of the conflict minerals bill. It’s true that ENOUGH has engaged in some very misleading advocacy but that shouldn’t be used to detract from a bill that has quite a few merits. Enough might have spoken the loudest but they were not the only voice on this issue. Considerable reflection and solicitation of expertise went into this bill and it should be assessed based on its content, not on the advocacy tactics that Enough used to support it.
  • Any decent level of research shows that the USGS has consistently underestimated the supply of minerals from the DRC by a huge margin, for years and years.
  • The issue is not the validity of the data emanating from the USGS. Should anyone talk to the researchers at the USGS and inquire about the methodology used for arriving at their numbers, one would quickly recognize that the numbers are arbitrary at best, especially regarding African countries.
  • They have been able to present to the predominantly white American audience the misanthropic message of savage Africans raping and killing as the primary driver of the conflict. American consumers then become best placed to save and raise hope for the African brute through conscious consumerism. The savage African and white savior narrative, which Nick Kristof calls “bridge character” work without fail.
  • This narrative eschews the main external drivers of the conflict and the devastating role that US foreign policy (the same type of foreign policy that resulted in Nelson Mandela being on the US terrorist list as late as 2008) and Western corporate practices have played in not only the conflict but the maintenance of the structural barriers of dependency and impoverishment in the heart of Africa
  • backing of the invasions of Congo by the Clinton administration "renaissance leaders"
  • Nor is the 14 years of pilfering by foreign multinationals even broached while companies such as the below stand to reap billions in profits for the next generation while Congolese wallow in misery and poverty- Rangold - AngloGold Ashanti - Banro
  • Even other opponents of Enough and Global witness, in the industry are shifting the argument to the fact that there cannot be a crackdown on tantalum from the DRC as it makes up too high a percentage of world supply.

AfricaFiles | D R Congo: Natural resource exploitation and human rights - 0 views

  • A number of foreign actors became directly involved in the exploitation of natural resources. The chaos and power vacuum brought about by the 1996 rebellion led to an opportunistic scramble for the DRC's resources. Everyone wanted a piece of the cake. Rebel groups and armies from neighbouring countries all helped themselves, some (such as Zimbabwe) with the blessing of the Congolese authorities, others (such as Rwanda or Uganda) by occupying territory by force or through proxy rebel groups, committing grave human rights abuses in the process
    • Arabica Robusta
       
      Fascinating that there is no mention here of those corporate networks through which coltan among others finds its way into cell phones.
  • Companies and individual traders who were prepared to trade in natural resources produced in these conditions, or to trade with groups with notoriously bad human rights records, can also be considered to have contributed to, or even enabled, these human rights abuses. In some cases, they were directly implicated.
  • Province Orientale Province Orientale held even greater promise in terms of natural resources. With its diamond fields, gold mines, vast expanses of forests with valuable timber and barely explored oil reserves, Province Orientale was, in some ways, the biggest prize.

Why Have a Virtual Receptionist? - 0 views

  •  
    Business owners take all possible steps to ensure customer satisfaction. One of the most successful and recommended strategies in this regard is to begin with a virtual receptionist service. This service brings in extra representatives for a business and eases the lives of the customers. When the customers have questions or queries to be answered or any problems to be solved, they try to reach the authoritative body telephonically and it is not uncommon for them for not having to been able to do so. This is where the need for virtual receptionists comes in. Virtual receptionists are basically persons who work for the customer support but do not work from the office or any specified location.
